It is normal to have a main place to gather. FFXI had Jeuno, WoW has Ironforge/Stormwind, FFXIV has Uldah, it is just the way it is.

Personally I am hanging around in Limsa Lominsa because of the armorer guild there, but Uldah is the main place to be to buy/sell stuff. I think when the other city opens that will be the main place to gather.
